nonlinear behavior
(OP)
Can someone provide a definition of nonlinear behavior for me? I have looked for a definition and have not been able to find one.
Thanks

RE: nonlinear behavior
RE: nonlinear behavior
1. Material nonlinearity as dhengr outlined above
2. Geometric nonlinearity
In general, linear approximations to problems are a good representation to actual physics when displacements, strains, temperature gradients, rotations etc are "small". (but there are exceptions)
A few examples of geometric nonlinearity: buckling of shells, stay cables of bridges, shallow arches with vertical loads, etc.
Here's a good write-up on the topic: http://en.
